Under the premise of range, other way can be, and in mechnical oscillator, pallet fork and inertial mass can be and be connected in
Two different elements together.
By means of mandrel 41, around the rotation axis X for being parallel to escape wheel 32-X’2Pivot axis X1-X1' pivot side
Formula installs pallet fork 2.
Understand for meaning herein, pawl is hook rostral (hooking beak), is also known as pawl in clock field
Stone.The upstream pawl 44 and downstream pawl 45 of the restriction pallet fork 2 of attachment 40.In this specification and in the appended claims,
Term " before ", " upstream " and " downstream " and similar term refer to the direction of advance of the tooth of the escape wheel at pawl.
It can be seen that in Fig. 4, attachment 40 includes rigid bodies 46, and rigid bodies 46 are rigidly attached to by rigging pilotage 47
In inertial mass 43.Pin 42 is by preventing these elements from participating in relative to each other around any possibility that rigging pilotage 47 pivots

It is rotated up, and its tooth (being indicated with D) encounters upstream pawl 44, and upstream pawl 44 does not stop it at once.
Then, specifically by the inertia of escape wheel 3 and by gear train 5 inertial drive tooth D promotion under, upstream arm 48 is flexiblely
Bending, be specifically flexiblely bent at its elastic bend part 54, this cause the kinetic energy of escape wheel 3 progressive absorption and
Similarly gradual speed reducing.When the hook fingers 52 of arm 48 encounter make it stop pin 42 when arm 48 flexible deformation terminate, this
Occur in Fig. 6.In this Fig. 6, escape wheel 3 is temporarily halted.
When the tooth D stopped by the damping of upstream pawl 44 occurs, pivot axis X of the pallet fork 2 around it1-X’1Pivot move
Dynamic reversed, the beginning of upstream pawl 44 after this is moved backward relative to escape wheel 3.This, which is moved backward, causes upstream pawl 44 remote
From tooth D, this releases escape wheel 3.Once away from tooth D certain distance, during stopping of the upstream arm 48 by being dissipated in its damping tooth D
The elastic potential energy of storage and the original form that it is presented again.
The forward movement of upstream pawl 44 moved backward along with downstream pawl 45 relative to escape wheel 3, escape wheel 3 is
Started to rotate again.This causes the case where indicating in Fig. 7, and wherein tooth D encounters downstream pawl 45.As previously mentioned, then tooth D exists
Gradually slow down in the first step, this followed by the result for being resiliently deformable downstream arm 49 in rebound direction.
When returning to section 58 and encountering the mandrel 41 for making its stopping, the flexible deformation of downstream arm 49 terminates.Mandrel 41 is then
The stopping function for downstream arm 49 is fulfiled, is illustrated in fig. 8.During stopping tooth D by the damping of downstream pawl 45, pawl
Pivot axis X of the fork 2 around it1-X’1Pivot movement it is reversed again.Once downstream arm 49 is by being dissipated in away from tooth D certain distance
It is damped stop tooth D during the elastic potential energy that stores and its original form is presented again.
Intermittent by pawl 44 and 45 pair escape wheel 3 stops being damped.This causes produced by the operation as release catch 1
Click sound largely reduce.
The present invention is not limited to previously described embodiments.Specifically, attached in also according to clock and watch pallet fork of the invention
Fitting 40 can be pivotally mounted on inertial mass 43 and so that it is restored to holding fix by additional spring, at this
In the case of kind, arm 48 and 49 can be rigid, or can be even omitted.
